Question

This is an urgent math question because I have limited time! Please help :)

Please show steps on how you go the answer
f(x) = −16x2 + 60x + 16

Part A: What are the x-intercepts of the graph of f(x)? Show your work.

Answer 1

This is urgent because I have maybe less than an hour rn

Answer 2

ok do 16 x 2 first then add that by 16 then whatever u get plug it in with 60x

Answer 3

i think thats how but i could be wrong

Answer 4

did you get it?

Answer 5

for some reason my brain does not like this math

Answer 6

and it is 16^2 sorry not 16x2

Answer 7

16x^2

Answer 8

To solve for the x intercepts, you need to find the value(s) where f(x) = 0

f(x) = −16x2 + 60x + 16
Factoring out -4

= -4(4x^2 - 15x - 4)
Factoring again (use the cross method)

= -4(x - 4)(4x + 1) = 0

From there, set (x-4) = 0 and (4x + 1) = 0 and solve for x
